Specification of Letters Patent.

Application filed June21, 1911 Serial No,,634,483.

To all whom it may concern:

Be it known that I, SVANTE ADOLF PET- TERSON, citizen ofthe United States, residing at Eureka, in county of Greenwood and State of Kansas, have invented certain new and useful Improvements in Tongue-Sup- I ports, of which the following is a specification. I

My invention'relates to an improvement 1n tonguesupports, and more partlcularly, for the tongue or pole of mowing machines,

o The invention consists in certain novel features of construction and combinations of parts which will be hereinafter fully. described and pointed out in the claims.

" In the accompanying drawings, Figure I l is aview in elevation showing the invention applied to a tongue or pole; and. Fig. 2 is a detail vertical sectional view through the support on the line 22 of Fig. 1.

A, represents the pole or tongue, and B, is i the supporting bar, whichbar is provided with a head 1 which is pivotally mounted be-o tween the plates 2, 2, connected to the sides of the bar. The lower surface of the head is rounded, as at 3,'atone'[edge, and is made 1 fiat or square at the opposite edge,;as at 4,

I whereby the bar is'capable of swinging latorally in one direction onlywith respect to the head, as the squared shoulder or portion a 4 causes the bar to be normally held rigid in a vertical position. clamp5 is pivotally connected to the head 1" and extends over and around thepole A and is fastened thereto by a screw bolt 6. r A bolt 7 c0n- V of support for the tongue when the machine;

I Copies of this patent may be obtained for five cents each, by addressing the Commissioner of intents; 5

n'ects the clamp 5 to the head 1, and connected'to the bolt is a coil spring 8, which in -turn is connected to the bar B for causing the bar to return to its normal or upright position .when swung laterally upon therhead 1. p A coil spring 9 is connected to the pole or tongue A, and to'the bar B for V normally holding the bar in a vertical posia sition when swungrearwardly. p

The object of thebar is to form. a means tion and for returning it to its vertical pof I or vehicle is at rest, to; relieve the weight from the draft animals. In harvesters,

mowing machines and the like, a great deal of the weight'of the machine'is thrown upon the horses or draft animals, and it is to overcome this difiiculty that I have, pro,-

vided' the pivoted bar orsupport'. The support has free movementwith respect to the tongue, so that in case of its coming in contact with an obstruction, itcan be swung rearwardly against the tension of'the s ring 7 9, but after passing over the obstruction it will be drawn back to its normal or vertical position, due to the tension of the spring 9. In instances where the support would strike obstructions, which wouldcause it to swing laterally, the spring 8 would be placed under '"greater tension, and after the obstruction had been passed, the spring would draw the bar or support to its normal position against the shoulder a.

Having fully described, my invention, what I claim asnew anddesire to secure by Letters Patent, is

l. The combination with a thereto, means pivotally" connecting the head to the pole whereby the support is capa-Q ble of movement in, a longitudinal and "lateraldirection, and means on the head for,

limiting the movement one of its movements. v o

2. The combination with a pole, ofasupport having a head pivotally connected of the support thereto, meanspivotally connecting the head to the pole 'whereby the support is capable of movement in a longitudinal and lateral direction, means on the head for l mlt ing the movement of the support inone of its movements,iand means for causing the,

support to return to its normal position; I

In testimony whereof I' aflix my slgnature, in the presence of two witnesses.
